I just placed a fixed odds multiples bet on the site (not the sportsbook pages). I had six selections and had a variety of multiple bets on them. When I submitted the bet, a countdown was shown. Before the countdown reached zero, the betslip refreshed and was shown empty. The 'bets placed' confirmation was simply missing, there was no message to show if my bets had been placed or not.
(The bets were in fact placed; they show up on the 'My Bets BETA' tab in the accounts)
BCM, perhaps you could pass this on to the developers, the site really should be showing the results of placing a bet.
